摘要
The present invention relates to a tooth form design method for a gerotor pump of designing the tooth form of an external rotor and an internal rotor by combining two ellipses and a gerotor pump designed through the same design method. The rotor tooth form for a gerotor designed by the present invention is named as ″SDICHOID III (product name)″, which is the dynamic and innovative tooth form curve, Samhan dynamic innovation choid III, developed by Samhan, the applicant of the present invention. According to a form of the present invention, the tooth form design method for a gerotor pump is a method for designing the tooth form of a gerotor pump for the lobe shape of an external rotor to have a shape where two ellipses are combined and includes: a step (S1) of, if the shape of a lobe (1a) of an external rotor (1) is a single shape of an ellipse, drawing a constitutive equation for the lobe shape of the external rotor; a step (S2) of drawing a shape function for the ellipse 1 by rotating and moving translationally the coordinate axis of the ellipse 1 obtained by the constitutive equation drawn in the step (S1) above and drawing a shape function for an ellipse 2 by moving the ellipse 1 symmetrically to the X-axis; a step (S3) of drawing contact point equations of the internal rotor and the external rotor for the ellipse 1 and 2 in the step (S2) above; and a step (S4) of calculating the shapes of the internal rotor and the external rotor from the contact point equations.;COPYRIGHT KIPO 2016
